If Win 10 is still installed, try starting in safe mode and check if it freezes etc.
If it works OK then it is a driver problem.
Check in Device Manager what the make and model number of the display adapter is.
I realize that you said that it froze as soon as you updated the video card driver, where did you get the driver from? Was it auto update find by Windows or manual install by you?
Try the display adapter manufacturer’s website and check what version Win 10 drivers they offer for the adapter model in your laptop and check if they work any better.
Also check in Event Viewer, for any Critical, Error or Warning events that stand out and "match" the times when the display freezes.
If you notice any, double click on them to get more information, and then search online using the Event ID number and the Source of the event to get more information as to what it means.
In Win 10 to get to Event Viewer, right click on the Windows Start button, on the left side of the Taskbar and click on the Event Viewer link.
Perhaps a start to finding out what is going on
